NUNITED STATES PATENT CET-ICE ANDRVV` J. FINNEGAN, OF MINNEAPOLIS, MINNESOTA.

IMPROVEMENT IN AIR-TIGHT PRESERVlNG-PACKAGES.

Specification forming part of Letters Patent No. 218,868, dated August 26, 187 9 5 application filed July 22, 187.).

To all whom it may concern.'

Beit known that I, ANDREW J. FINNEGAN, of Minneapolis, in the county of Hennepin, and in the State of Minnesota, have invented certain new and useful Improvements in Air- Tight Preserving-Packages; and` I do hereby declare the following is a full, clear, and exact description of the same.

This invention relates to improvements on a patent granted to me November 2l, 1876, under No. 184,605, for a butter-package#7 and it consists of the combination, with the package described, having air-tight cover A B O I) and fastening K, of the wooden (preferably maple) lining E and the central provision-chamber, G, having a tight Cover, there being a space between the provision-chamber and the lining for ice or other cooling material.

In order to enable others skilled in the art to which my invention appertains to make and use the same, I will now proceed to describe its construction and operation, referring to the accompanying drawings, in which- Figure l is a `part-sectional view of a package adapted for the preservation of butter, furs, herbs, and other articles. Fig. 2 is a partsectional View of a refrigerator-package for the preservation of fruit, roll-butter, or Fig. 3 is a detail of the cover and side of the package.

The body F of the package is constructed in a cylindrical form, of any suitable` lnaterial and dimensions, and is provided with a ian ged base, as in the before-mentioned patent; but,

in addition to the outer wall, an inner lining, E, is provided, which extends around thebody of the package, and is made of any suitable material that is a non-conductor of heat, such as wood or paper.

I is the bottom flange; F J, the bottom of package 5 A B D C, the airtight cover, all as described and claimed in my said Patent No. 184,605.

In Fig. 2 a modification in the construction of the package is shown,by which it is adapted as a refrigerator-package for the preservation ot' fruit or rollfbutter, or other similar articles extremely sensitive tothe deteriorating action of heat. In this form of the package the article to be preserved is placed within an inner chamber, G, between the sides of which chamber and the outer shell ofthe package an icespace, H, is provided, into which space broken ice is packed.

The lining` E being anon-conductor of heat, and the package being air-tight, the wasteful melting ofthe ice is prevented, and the butter or other articles are thus preserved in a firm, fresh condition.

The inner chamber is provided with a cover, and may be made of any suitable material.

The advantage of my improvements is, that' articles of any description can be preserved from the destroying' action of the air, insects, heat, &c.,in a thoroughly practical,protable, and simple manner.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is- A The combination, with the package described, having air tight cover A B (l l) and fastening K, of the wooden (preferably maple) lining E and the central metallic provisionchamber, G, having a tight-fitting cover, there being a space between the provision-chamber and the lining for ice or other cooling material, all substantially as described, and for the uses and purposes set forth.

ln testimony that I claim the foregoing I have hereunto set my hand this 18th day of July, 1879.
